| abstractText | A cDNA clone coding for the murine IgG1 induction factor has been isolated. The translation products directed by this clone were analyzed in different biological assays. The data obtained show that the IgG1 induction factor: Is involved in the regulation of IgG responses, by increasing IgG1 and decreasing IgG3 and IgG2b secretion; Induces hyper-Ia expression on resting B lymphocytes; Synergizes with anti-Ig in inducing DNA synthesis in resting B lymphocytes; Synergizes with DxS in inducing DNA synthesis by B lymphocytes; It induces DNA synthesis by either the T cell line CTL-L or Con-A blasts. Thus, this lymphokine in addition to IgG1 inducing activity has also BSF-1, BCGF-II and TCGF like activities. The fact that a single molecule can perform all the above listed functions has implications for our view of lymphocyte activation. It indicates that considering the B cell response as an ordered series of independently controlled events, is an oversimplified view of the dynamic process through which B cells are activated and also indicate the functional interconnection of the different elements of the immune system. |
